//! \brief Class for evaluating curve segments as lines over time. 
/*!
	A MDynSweptLine provides access to a curve segment defined as a line.
	It can only be accessed with the MFnDynSweptGeometryData class
	that is provided as an output from the geoConnector node.

	The class provides parametric time evaluation for a curve.
	Time is in the range 0 to 1, where 1 represents the current frame and 0
	represents the previous frame. In this way you can get interpolated
	values of a curve in motion.
